SPECIFICATION forming part of Letters Patent. N o. 720,150, datedFebruary 10, 1903.

` Application tiled February 28, 1902. Serial 110.96.185. (No model-l Toa/ZZ wwwt it 7er/ty concern:

Be it known that I, JOHN lNeLEBY, a suhject of the King of Great Britainand Ireland, and a resident of Leeds, in the county of York, England,have invented a certain new and useful Improvement in ContinuousPresses, of which the following is a specication.

The object of the present invention is to provide a lirm bed which continnously travels in one direction over a definite length, the tablebeing constantly renewed at one end and shortened at the other end asfresh material comes onto it or leaves it. In. other words, the mainobject is to secure the advantages as regards regularity and contin nityof motion which are oifered by flexible bands or tables, with theadvantages of rigidity and strength, such as have hitherto been obtainedonly by the use of xed or reciprocating or intermittently-moved tables.

Tables constructed to attain the above object are well adapted formachines used in the manufacture of linolenm, where the maferial is fedonto orunder to a textile backing and afterward subjected to greatpressure, for the pressing and waterproofing of cloth,for sheet-ironingand other machines where the sheet of material to be made or pressed isvery many times the length available for a carrying and pressing table.

I attain the above object by constructing such tables of a series ofblocks supported on suitable guides or slides and which are advancedfrom the rear or feed end by a pushing motion between the blocks, theforemost block being removed from the front by raising or lowering it,while an extra block is added to the rear by lowering or raising it bythe tilting in one direction of a long balanced lever or levers carryingpro tempore the said blocks, While during the interval prior to thetilting of the said lever in the opposite direction the withdrawn blockis traversed above or below thevtable back to the starting end, theadvance of the rest of the blocks being regularly and uninterruptedlycontinued during the whole of the time by rack-and-pinionorscrew-and-nutmechanism. Theinvention comprises means for moving theblock being added up to and into contact with the one in front of'it andinto connection with the said advancing mechanism without shock and forremoving the foremost block without any rubbing or sliding of its rearedge against the front of the block next behind it. These means areillustrated bythe accompanying drawings, to which reference is had inthe following description.

Figure l is a plan, the lower half having the blocks and the advancingscrew lnechanism and crossgnides removed to show more clearly the sidelever and the return-slides; Fig. 2 is a longitudinal elevation andsection on line A B C D E F of Fig. l. Figs. 3, 4, and 5 arediagrammatic elevations showing the positions of the various parts during the other three parts of the cycle in which the machine operates.

a indicates the outer side frames of the inachine carrying thecross-girders Z), on which rest the longitudinal slide-pieces c,carrying the table-blocks d, which latter are accurately guided duringtheir advance in the direction indicated by the arrow in Fig. l. To thesides of each block are connected half-nutse of considerable length, inwhich the screwed part of the the shaftf works as the half-nuts passunder the same. The rest of the screwshaft is turned down to the bottomof the screw-threads, so that the plain part rests on the top of thethreads of the half-nuts and is held down and steadied by plainsemicircular caps g, which allow the half-nuts to pass beneath them. Itwill be evident that the blocks in front of the screwed part of theshaftsf are moved only by the pushing action of the blocks behind them,whereby the close contact of adjoining edges of the blocks is insured.The shafts j' may be rotated by wormwheels h and worms t' on thecross-shaftj, the latter being driven byany convenient means orconnections in a positive manner from the main driving-shaft 7c.

Z Z indicate a pair of two-armed levers carrying at their ends, by meansof sidelinksm, cross-bar 71., and cross-head piece o, the platens p toreceive and respectively lower and raise the blocks d. In order to guidethe crosshead piece o vertically and to insure that the foremost blockiswithdrawn without any rubbing movement front edge of the next-followingblock, the cross-bars n and q are connected to links r, hinged to thcend standards s, so as to conof its rear edge against the i stitute,with the cross-head piece o, a parallel motion, the horizontal movementof which has during the proper time a greater speed than that of theadvance of the blocks due to the screws f. The time just referred to isthat during which the foremost block is moving out of line with the restof the blocks. The movement of the levers Zis effected in the onedirection from the cam t on the main driving-shaft Zo by means of the'two-armed lever u, the one end of which carries a cam pin or roller oand the other end a double fork w, embracing the top cross-bar q, themovement in the opposite direction being effected by a weight attachedeither to the levers Z or the lever tt. The block to be added is pushedoff the platen and up to the preceding block and held there until itshalf-nut is properly engaged with the screwed part of the shaft f bymeans of connecting-rods carrying between them a frame e', in which isfitted, capable of a slight sliding motion, the pusher-bar 1, with aspring 2 between it and the frame z. The block, withdrawn from the frontend and dropped down to the level of the return longitudinal slides 3,is pushed off its platen and onto and along the returnslides 3 by thespring-cushioned pushers 4, which are clamped to the two wire ropes 5,the latter passing around the guide-pulleys 6 and with both their endscoiled in opposite directions several times around and secured to thedriving-drums 7. These driving-drums 7 are reciprocated from the maindrivingshaft k by means of the crank-pin gear-wheel 8, connecting-rod 9,sliding rack 10, andrackpinion 1l on the axle of the drums 7.

'Ihey working of the machine is clearly indicated by Figs. 2, 3, 4, and5. In Fig. 2 the foremost block d has just been dropped by its platenand is ready to be pushed onto and along the return-slides 3, while theblock (Z7 to be added has just been raised by the corresponding platento the level of the top slides c and ready to be pushed forward by thepusher-bars. In Fig. 3 the leversZ and platens p have reverted,respectively, to their former positions, the withdrawn block having inthe meantime returned along the lower slide and is being pushed onto theplaten at the rear end of the machine, and the block being added hasbeen pushed so far along the top slides as to be independent of thesupport of the dropped platen, while the now foremost block is beingpushed over the lowering or withdrawing platen. In Fig. 4 theretnrn-pushers 4 are moving back to reach their starting position beforethe now foremost block is completely carried by the corresponding platenand must reach such starting position before the said platen hascompleted its descent and the other platen its rise, as shown in Fig. 5.

It will be evident that the half-nuts e may be replaced by racks and thescrews f by pinions gearing with said racks, also that the ropes orchains 5, provided with pushing projections and driven at the properspeed, may be arranged to be driven continuously in the return-pushingdirection or intermittently instead of being reciprocated.

Having now described my invention, what I claim, and desire to secure byLetters Patent, is
